Specification of Letters Patent.

Patented Jan. 17, 1911.

Application filed May 20, 1909, Serial No. 497,223. Renewed June 24, 1910. Serial No. 568,714.

To all whom it may concern:

Be it known that I, IVEBSTER L. MARBLE, a citizen of the United States, residing at Gladstone, in the county of Delta and State of Michigan, have invented new and useful Improvements in Looks for Multibarreled Guns, of which the following is a specification. v

This invention relates to firearms, and its object is to provide an improved lock for double or multi-barreled guns, whereby both barrels can be fired in succession by one trigger. The barrels are arranged in a vertical tier, one above the other. The cartridges are fired by spring plungers, arranged one above the other, and retained in their retracted or cocked positions by means of spring pawls or latches, which can be tripped in succession by the operation of the single trigger.

In the accompanying drawings, Figure 1 is aside elevation of a gun showing my iniproved lock, the cover for the lock being in section to disclose the mechanism. Fig. 2 is a side elevation of the lock showing the upper plunger retracted. Fig. 3 shows the lower plunger retracted. Fig. 4 is a top plan view of the upper latch. Fig. 5 is a vertical section on the line 55, Fig. 3, and Fig. 6 is a side View of a plunger.

The invention is illustrated as applied to a small gun for the use of woodsmen, campers, automobilists, and the like, having two barrels 1 and 2 arranged one above the other; the upper one being preferably a rifle barrel and the lower one for shot. The gun is a breech loader, and is preferably provided with a folding stock 8 pivoted to the grip handle a.

Mounted in the breech and in line with the two barrels are two tubular guides 5, in each of which slides a plunger 6, which carries at its front end a pin 7 to explode the cartridge. The rear end of the plunger projects beyond the breech frame, and is provided with a head 8 to facilitate its retraction. A helical spring 9 surrounds the plunger and abuts at one end against the breech frame and at the other against a collar 10 on the plunger. A pin 11 projecting laterally from said plunger plays in a longitudinal slot in the tubular guide 5, and is adapted to be engaged by a spring latch 12 when the plunger is retracted. The latch is pivoted at its front end to one side of the guide or to a block 18 secured thereto. A flat spring 14 is attached to said block and bears upon a lug 15 on the side of the latch. Said lug plays up and down in a notch in the guide, so as to limit the downward movement of the free end of the latch.

The trigger 16 is pivotally attached at its rear end to an upright slide 17, which is provided with two shoulders 18 respectively adjacent to the ends of the two latches. One

of said shoulders, as for instance, the upper one is in close contact with its latch, but between the other shoulder and its latch there is normally a slight space. The result is that when the trigger is pulled, it operates to lift the slide and the upper latch simultaneously, while the lower latch remains stationary until the slide has been raised suificiently to bring the lower shoulder into contact with its latch. By that time, the upper latch will have been tripped and the barrel discharged. A continued movement of the trigger will result in raising the slide high enough to trip the lower latch and discharge the lower barrel. It thus appears that if both barrels are cooked, they can be discharged successively, the upper one first. If only one barrel is cooked, it can be fired without affecting the other. Fig. 2 shows the upper plunger alone retracted, and Fig. 3 shows the lower plunger alone retracted. In either case, the pulling of the trigger will fire only the barrel selected.

The slide is vertically slotted to engage with a stationary stud 19 by which it is guided in its movements. The sides of the tubular guides may be flattened somewhat, as shown, to render the construction more compact. At the front end of each of the longitudinal slots in which the pins 11 play, there is a lateral notch 20 in which said pins can be engaged by slightly rotating the plungers after retracting them'a little (see lower barrel in Fig. 5). In this position, the firing pins are withdrawn sufficiently to permit the gun to be broken down, without danger of injury to said pins. Moreover, in this position, the gun is at safety and can be carried without danger of accidentally exploding a cartridge.

I am aware that guns have been proposed in which two or more barrels can be discharged by one trigger, and I do not claim this broadly. But

That I do claim and desire to secure by Letters Patent is 1. A look for multi-barrel guns, comprising spring plungers arranged in a vertical tier, a laterally projecting pin on each plunger, a latch pivoted near the forward end of each plunger and extending rearwardly to engage With the pin on said plunger When retracted, an upright slide arranged at one side-of said plungers and having shoulders adapted to trip said latches in succession, and a single trigger for operating said slide.

2. A lock for multi-barrel guns, comprising spring plungers arranged in a vertical tier, a slotted guide for each plunger, having a lateral notch, and a pin on said plunger adapted to enter said notch when said plunger is slightly retracted and rotated a little.

3. A lock for multi-barrel guns, comprising' tubular guides provided with longitudinal slots, a plunger in each guide, a helical spring acting on said plunger, a pin on the plunger projecting through said slot, a spring latch. adapted to engage with said pin When said plunger is retracted, a slide adjacent to said latches and having shoulders adapted to make contact therewith at different times in its movement, and a single trigger for operating said slide.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
